Back up files 

   1.  All users of the volume set must be initially logged off before an
       split-volume backup of that set can be performed.

       Use the VSCLOSE command with the SPLIT option to split the volume
       set into user volumes and backup volumes:
_______________________________________
|                                     |
|                                     |
|      :TELL @ LOGOFF FOR BACKUP      |
|      :VSCLOSE PROD_SET; SPLIT       |
|                                     |
_______________________________________

            

   2.  Use the VSOPEN command to make the volume set available.  Both
       user volumes and backup volumes attempt to be mounted.  If either
       of them has been taken offline, the command only mounts the
       available volume set half.  After the volume set is placed
       split-volume using the VSOPEN command, it is mounted.

   3.  Notify users that the volume set is available for use:

|                                                      |
|      :VSOPEN PROD_SET                                |
|                                                      |
|      PROD_SET SPLIT USER VOLUME MOUNTED ON LDEV 32   |
|      (AVR 23)                                        |
|                                                      |
|      PROD_SET SPLIT BACKUP VOLUME MOUNTED ON LDEV 33 |
|      (AVR 24)                                        |
|                                                      |
|      :TELL @ SYSTEM IS AVAILABLE NOW                 |
|                                                      |
________________________________________________________

            

       _________________________________________________________________ 

       NOTE  Once a volume set has been taken offline with a VSCLOSE
             command, it can only be mounted with a VSOPEN command, not
             by bringing it online.

       _________________________________________________________________ 

   4.  Use the STORE command with the SPLITVS parameter to back up the
       volume set.  The tape produced by a split volume STORE command is
       fully compatible with that from a normal STORE command:
_________________________________________________
|                                               |
|                                               |
|      :FILE T; DEV=TAPE                        |
|      :STORE @.@.@; *T; SPLITVS=PROD_SET; SHOW |
|      .                                        |
|      .                                        |
|                                               |
_________________________________________________

            

   5.  Invoke VOLUTIL.

   6.  Use the JOINMIRRSET command to join the user and backup halves of
       a split volume set to make them mirrored again.  After the volume
       set is joined, a repair starts using the volumes that were
       specified by the source parameter as the source volumes.

|                                                       |
_________________________________________________________

            

       The SOURCE=USER option is specified so that users can continue
       accessing the volume set while the join is initiated and the
       repair takes place.
